BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a liquid crystal display and inparticular, to a transflective liquid crystal display.

(b) Description of the Related Art

A typical liquid crystal display (“LCD”) includes an upper panel havinga common electrode and an array of color filters, and a lower panelhaving a plurality of pixel electrodes and thin film transistors(“TFT”s). A pair of aligning films are coated on the upper and the lowerpanels, and a liquid crystal layer is interposed between the aligningfilms of the upper and the lower panels. The orientations of moleculesof the liquid crystal layer are changed by adjusting an electric fieldgenerated by the potential difference between the pixel electrodes andthe common electrode, which are applied with appropriate voltages. Thechange of the orientations of the liquid crystal molecules causes thetransmittance of light passing through the LCD to be varied, therebyobtaining desired images.

During the fabricating process of such a conventional LCD, impurity ionsare often generated and remained on the surface of the aligning films.After the fabricated LCD operates for a time, these impurity ions travelalong an alignment direction formed by rubbing the aligning films, togather at one corner of the liquid crystal display. As a result, thiscauses a defect that one corner of a display area is bright whendisplaying dark images.

A TFT array panel for an LCD according to an embodiment of the presentinvention is described more in detail with reference to FIGS. 1-6.

With reference to FIGS. 1 to 4, the TFT array panel 1 will be describedin detail.

A plurality of gate lines 121 for transmitting gate signals (or scanningsignals) are formed on an insulating substrate 110. Each gate line 121extends substantially in a transverse direction and a plurality ofportions of each gate line 121 form a plurality of gate electrodes 123.Each gate line 121 includes a plurality of expansions 127 protrudingdownward.

The gate lines 121 include a low resistivity conductive layer preferablymade of Ag containing metal such as Ag and Ag alloy or Al containingmetal such as Al and Al alloy. The gate lines 121 may have amultilayered structure including a low resistivity conductive layer andanother layer preferably made of Cr, Ti, Ta, Mo or their alloys such asMoW alloy having good physical, chemical and electrical contactcharacteristics with other material such as indium tin oxide (ITO) andindium zinc oxide (IZO). A good exemplary combination of such layers isCr and Al—Nd alloy.

The lateral sides of the gate lines 121 are tapered, and the inclinationangle of the lateral sides with respect to a surface of the substrate110 ranges about 30-80 degrees.

A gate insulating layer 140 preferably made of silicon nitride (SiNx) isformed on the gate lines 121.

A plurality of semiconductor stripes 151 preferably made of hydrogenatedamorphous silicon (abbreviated to “a-Si”) or polysilicon are formed onthe gate insulating layer 140. Each semiconductor stripe 151 extendssubstantially in a longitudinal direction and has a plurality ofextensions 154 branched out toward the gate electrodes 123. The width ofeach semiconductor stripe 151 becomes large near the gate lines 121 suchthat the semiconductor stripe 151 covers large areas of the gate lines121.

A plurality of ohmic contact stripes and islands 161 and 165 preferablymade of silicide or n+ hydrogenated a-Si heavily doped with n typeimpurity are formed on the semiconductor stripes 151. Each ohmic contactstripe 161 has a plurality of extensions 163, and the extensions 163 andthe ohmic contact islands 165 are located in pairs on the extensions 154of the semiconductor stripes 151.

The lateral sides of the semiconductor stripes 151 and the ohmiccontacts 161 and 165 are tapered, and the inclination angles thereof arepreferably in a range between about 30-80 degrees.

A plurality of regular and dummy data lines 171 and 172, a plurality ofdrain electrodes 175, and a plurality of storage capacitor conductors177 are formed on the ohmic contacts 161 and 165 and the gate insulatinglayer 140.

The data lines 171 and 172 for transmitting data voltages extendsubstantially in the longitudinal direction and intersect the gate lines121. A plurality of branches of each data line 171 and 172, which extendtoward the drain electrodes 175, form a plurality of source electrodes173. Each pair of the source electrodes 173 and the drain electrodes 175are separated from each other and opposite each other with respect to agate electrode 123. A gate electrode 123, a source electrode 173, and adrain electrode 175 along with an extension 154 of a semiconductorstripe 151 form a TFT having a channel formed in the extension 154disposed between the source electrode 173 and the drain electrode 175.

The storage capacitor conductors 177 overlap the expansions 127 of thegate lines 121.

The data lines 171 and 172, the drain electrodes 175, and the storagecapacitor conductors 177 also include a low resistivity conductivelayer, but they may have a multilayered structure including a lowresistivity conductive layer and another layer having good physical andchemical contact characteristics. The lateral sides of the data lines171 and 172, the drain electrodes 175, and the storage capacitorconductors 177 are also tapered, and the inclination angle of thelateral sides with respect to a surface of the substrate 110 rangesabout 30-80 degrees.

The ohmic contacts 161 and 165 interposed only between the underlyingsemiconductor stripes 151 and the overlying data lines 171 and 172 andthe overlying drain electrodes 175 thereon and reduce the contactresistance therebetween. The semiconductor stripes 151 include aplurality of exposed portions, which are not covered with the data lines171 and 172 and the drain electrodes 175, such as portions locatedbetween the source electrodes 173 and the drain electrodes 175. Althoughthe semiconductor stripes 151 are narrower than the data lines 171 and172 at most places, the width of the semiconductor stripes 151 becomeslarge near the gate lines as described above, to enhance the insulationbetween the gate lines 121 and the data lines 171 and 172.

A passivation layer 180 is formed on the data lines 171 and 172, thedrain electrodes 175, the storage conductors 177, and the exposedportions of the semiconductor stripes 151. The passivation layer 180 ispreferably made of photosensitive organic material having a goodflatness characteristic, low dielectric insulating material such asa-Si:C:O and a-Si:O:F formed by plasma enhanced chemical vapordeposition (PECVD), or inorganic material such as silicon nitride. Thepassivation layer has unevenness on its top surface.

The passivation layer 180 has a plurality of contact holes 185, 187 and189 exposing the drain electrodes 175, the storage conductors 177, andend portions 179 of the data lines 171 and 172, respectively. Thepassivation layer 180 and the gate insulating layer 140 has a pluralityof contact holes 182 exposing end portions 125 of the gate lines 121.

A plurality of regular and dummy pixel electrodes 190 and 195 and aplurality of contact assistants 92 and 97 are formed on the passivationlayer 180. The regular pixel electrodes 190 are disposed on the displayarea 5, while the dummy pixel electrodes 195 and the contact assistants92 and 97 are located on the peripheral area 6.

Each pixel electrode 190 or 195 includes a lower transparent electrode191 preferably made of ITO or IZO and an upper reflective electrode 192having high reflectance such as Ag and Al, and has embossment due to theunevenness of the passivation layer 180. As shown in FIGS. 3 and 4, thereflective electrode 192 of the regular pixel electrode 190 has a hole Texposing the transparent electrode 191, while that of the dummy pixelelectrode 195 has no hole as shown in FIGS. 5 and 6.

The pixel electrodes 190 and 195 are physically and electricallyconnected to the drain electrodes 175 through the contact holes 185 andto the storage capacitor conductors 177 through the contact holes 187such that the pixel electrodes 190 and 195 receives the data voltagesfrom the drain electrodes 175 and transmits the received data voltagesto the storage capacitor conductors 177. The pixel electrodes 190 and195 supplied with the data voltages generate electric fields incooperation with a common electrode on the color filter array panel 2supplied with a common voltage, and the electric fields reorient liquidcrystal molecules disposed between the pixel electrodes 190 and 195 andthe common electrode.

A pixel electrode 190 and 195 and the common electrode form a capacitorcalled a “liquid crystal capacitor,” which stores applied voltages afterturn-off of the TFT. An additional capacitor called a “storagecapacitor,” which is connected in parallel to the liquid crystalcapacitor, is provided for enhancing the voltage storing capacity. Thestorage capacitors are implemented by overlapping the pixel electrodes190 and 195 with the gate lines 121. The capacitances of the storagecapacitors, i.e., the storage capacitances are increased by providingthe expansions 127 at the gate lines 121 for increasing overlappingareas and by providing the storage capacitor conductors 177, which areconnected to the pixel electrodes 190 and 195 and overlap the expansions127, under the pixel electrodes 190 for decreasing the distance betweenthe terminals.

The pixel electrodes 190 and 195 overlap the gate lines 121 and the datalines 171 to increase aperture ratio but it is optional.

The contact assistants 92 and 97 are preferably made of ITO or IZO,located on the pad areas 7 and 8, respectively, and connected to theexposed end portions 125 of the gate lines 121 and the exposed endportions 179 of the data lines 171 through the contact holes 182 and189, respectively. The contact assistants 92 and 97 are not requisitesbut preferred to protect the exposed portions 125 and 179 and tocomplement the adhesiveness of the exposed portion 125 and 179 andexternal devices.

An aligning film 11 forms an uppermost layer of the TFT array panel 1 asshown in FIG. 2, and the aligning film 11 is rubbed in a directionindicated by arrows shown in FIG. 1, i.e., in the direction from theupper left to the lower right.

Next, the color filter panel 2 will be described with reference to FIGS.1 and 2.

A black matrix 220 preferably made of an organic material is formed onan insulating substrate 210 preferably made of transparent glass. Theblack matrix 220 surrounds and defines the display area 5. The blackmatrix 220 overlaps the dummy pixel electrodes 195 in the dummy pixelareas DP. Although it is not shown, the black matrix 220 screens theborders between the regular pixel electrodes 190 to define the pixelareas AP and to prevent light leakage between the pixel areas AP. Red,green and blue color filters (not shown) are formed in respective pixelareas AP of the display area 5. A common electrode 270 preferably madeof transparent conducting material is formed on the color filters andthe black matrix 220 and covers the entire area of the substrate 210. Analigning film 21 forms an uppermost layer of the color filter panel 2,and the rubbing direction thereof is the same as that of the aligningfilm 11 of the TFT array panel 1.

As can be seen in FIGS. 1 and 2, since the TFT array panel 1 is largerthan the color filter panel 2, the pad areas 7 and 8 are located outsidethe color filter panel 2. The sealant 4 is located external to thedisplay area 5 and interposed between the two panels 1 and 2. Thesealant 4 partly overlaps the black matrix 220.

The gate PCB 450 and the data PCB 550 are electrically connected via theFPC film 600 therebetween for signal transmission. Signal paths 451, 551and 552 preferably made of conducting wires for transmitting signals areprovided on the PCBs 450 and 550 and the FPC film 600 therebetween. AnLCD controller 700 is provided on the data PCB 550 but it may beprovided on the gate PCB 450. A driving voltage generator (not shown) isalso provided on the gate PCB 450. The driving voltage generator 900generates a gate-on voltage, a gate-off voltage and a common voltage. Agray voltage generator (not shown) generating a plurality of grayvoltages is provided on the data PCB 550. At least one of the gate PCB450 and the data PCB 550 may be omitted, and then the associatedcircuits and signal paths may be formed in the TFT array panel 1.

A plurality of gate driving integrated circuits (ICs) 410 and the datadriving ICs 510, preferably made in chips, are mounted on the gate TCPs400 and the data TCPs 500, respectively. A plurality of leads (notshown) connected between the gate driving ICs 410 and the signal path451 and between the gate driving ICs and the gate lines 121 are formedon the gate TCPs 410. Another plurality of leads (not shown) connectedbetween the data driving ICs 510 and the signal paths 551 and 552 andbetween the data driving ICs 510 and the data lines 171 and 172 areformed on the data TCPs 500. Reference numerals 520 and 521 shown inFIG. 1 indicate the leads for transmitting signals for the dummy datalines 172, which are connected to the signal path 552.

The gate TCPs 400 and the data TCPs 500 are respectively attached to thegate PCB 450 and the data PCB 550 to be electrically connected thereto,and are attached to the panel assembly 300 to be electrically connectedto the gate lines 121 and the data lines 171 and 172, respectively.Alternatively, the gate driving ICs 410 and/or the data driving ICs 510are mounted on the TFT array panel 1, which is called a COG (chip onglass) type. Alternatively, the gate driving ICs 410 and/or the datadriving ICs 510 are substituted with driving circuits formed in the TFTarray panel 1, which are made of the same layers as the gate lines 121,the data lines 171 and 172 and the TFTs.

The LCD controller 700 provides a plurality of red, green and blue imagesignals for the data driving ICs 510 and a plurality of control signalsfor the driving ICs 410 and 510 via the signal paths 451, 551 and 552 onthe PCBs 450 and 550 and the FPC film 600 to control the driving ICs 410and 510. The gate driving ICs 410 generate the scanning signals based onthe gate-on voltage and the gate-off voltage from the driving voltagegenerator 900 to apply to the gate lines 121 via the end portions 125thereof in synchronization with the control signals from the LCDcontroller 700. The data driving ICs 510 select the gray voltages fromthe gray voltage generator based on the image signals from the LCDcontroller 700 to apply as the data signals to the appropriate datalines 171 and 172 via the end portions 179 thereof in synchronizationwith the control signals from the LCD controller 700.

In this LCD, the impurity ions on the surface of the aligning films 11and 21 travel along the rubbing direction, and gather at the dummy pixelelectrodes 195, in particular, near the lower right corner. As describedabove, since the dummy pixel electrodes 195 in the rightmost columnsoverlap the black matrix 220, the area with defect image caused by suchions is screened by the black matrix 220. Furthermore, the dummy pixelelectrodes 195, which have no transmissive area, block the light from alight source. Accordingly, the LCD according to this embodimentcompensates the defects in the dummy pixel areas DP.

According to another embodiment of the present invention, the rightmostregular pixel electrodes 190 are elongated along the gate lines 121 tooverlap the black matrix 220 without providing the dummy pixelelectrodes. The elongated portions of the pixel electrodes 190 have notransmissive area.
